English as a lingua franca (ELF) represents a substantial paradigm shift in ELT because it challenges the traditional norm of standard English. Despite this changing trend, there is a gap in research on incorporating ELF into in-service teachers' professional development (PD). Given the backdrop that (trans)disciplinary courses are expected to be…

This paper explores secondary school students' investment in their language learning after having graduated from one of four bilingual (also termed Content and Language Integrated Language (CLIL)) primary school programs in New South Wales (NSW), Australia. We show the different study pathways pursued by a selection of students and illustrate…

Research syntheses that evaluate bilingual program effectiveness have grown exponentially since the 1980s. Contradictory to earlier anti-bilingual findings, these research syntheses, including statistical meta-analyses, have converged on findings supporting L1 teaching. This study examines the methodological soundness of eight statistical…

The main goal of this paper is to suggest a combination of data analyses -- notably generalized additive models, time-series clustering methodology, visual methods for significance testing and qualitative analyses -- that relate to Complex Dynamic Systems Theory (CDST). To this end, we report on findings from a larger project conducted in a…

This study explores the bases of achievement invoked by teachers when assessing students' work in the context of a bilingual education program where academic subjects are taught through English as a foreign language. During a professional development seminar, teachers judged samples of students' writing in response to tasks that elicited the three…

This study explores working business professionals' perspectives towards the implementation of two-way language immersion programs in Texas public schools. Participants were selected for participation by means of a pre-selection survey that assessed various aspects of the cultural, educational, linguistic, familial, and business background of the…

Because dual-language books (DLBs) print the entire text in two languages nearby on the page, they have great potential for supporting children's biliteracy development by providing contexts to compare/contrast languages. However, little is known about how children read DLBs independently and how they may/may not use such characteristics to…

Reclassification is a crucial educational student outcome when a school system determines that a student is English proficient and ready for mainstream instruction without language support services (Umansky et al., 2020). This study examined the relationship between crucial and complex language ideologies of dual language teachers and the…

This case study explored Spanish-speaking educators' perceptions and experiences of dual-language immersion (DLI) professional learning (PL). The study aimed to understand how PL offerings could best support and meet the needs of DLI Spanish teachers' best practices in the target language. The perceptions and experiences of seven Spanish DLI…

This qualitative study highlights the nuances behind apparent internal linguistic discrimination by Latinx bilingual teachers toward their Latinx students' Spanish. Using a teacher solidarity lens and building on prior work in language ideologies and minoritized bilingual teacher identities, we conducted semi-structured interviews with 15 U.S. and…

As Two-Way Dual Language Programs continue in their nascent stages in the United States, some teachers, administrators, and researchers have reported issues of interest convergence. This construct refers to a Critical Theory principle that proposes alignment between the interests of whites and marginalized groups for a perceived common benefit,…

Research on Content and Language Integrated Learning (CLIL) programmes has shown that teachers find it difficult to integrate content and language in their teaching, and that this may be due to a lack of a specific type of teacher language awareness (TLA) for this type of teaching. This study explores how TLA for CLIL is manifested in metatalk in…

Bilingual education that incorporates a local language alongside the official language has become an increasingly common approach in sub-Saharan Africa for improving literacy rates and learning outcomes. Evidence suggests that bilingual instruction is largely associated with positive learning and literacy outcomes globally. However, the adoption…

Sentence frames are a frequently used form of pedagogical scaffolding in language education. Yet there is debate around whether sentence frames offer the opportunity for analysis and internalisation of authentic language use, or simply facilitate rote, 'plug and play' language use. This paper takes a linguistic ethnography approach informed by…

This volume proposes solutions to the gentrification of dual language, bilingual and immersion education by examining how it operates across diverse school and community contexts. It brings together studies in a number of areas including instruction, curriculum development, classroom interaction, school leadership, parent and community engagement,…
